FAA Ground School Practice Test

Under which conditions are flight crew members specifically required to keep their safety harnesses fastened?

1. Only during taxi

2. While en route only

3. During takeoff and landing only

4. During takeoff and landing, and while en route

The correct answer is: During takeoff and landing only

Flight crew members are specifically required to keep their safety harnesses fastened during takeoff and landing due to the critical phases of flight where the risk of incidents is higher. Takeoff and landing are generally considered the most hazardous parts of a flight, with the potential for abrupt movements, turbulence, or emergency situations that could arise. Therefore, being securely fastened during these times ensures that crew members can remain in their seats and respond effectively if an emergency occurs. While it is certainly good practice for crew members to wear their harnesses during other phases of flight, such as while en route, the regulation specifically highlights takeoff and landing because these are moments when their ability to react to situations can be crucial for both their safety and the safety of passengers. Crews are also encouraged to keep their harnesses fastened at other times, but there are no standard requirements in place for that like there is for takeoff and landing.
